Sorry to hear about that. I also had an issue with my application when I mailed it because there was no mention of the $10 processing fee. Unfortunately the Vietnamese govt doesn’t seem to care to clearly spell out their policies or update them whenever they change. If I were traveling to Vietnam in less than a month’s time…I would definitely not apply for something like a Visa Exemption which requires you to mail in your passport. You can never be sure anything will get done in time…whether it is the VN government or the .
